BICYCLE-JACK. y

' SPECIFICATION forming part of Letters Patent No. 506,495, dated Octoberl, 1893.v v 'y I I y Application iiledvOctober 6, 1892. `Serial No. 447.934. (No model.) v

- To all wiz/ont it may concern:

Be n known' ,that r, WILLIAM H. HART, Jr.,

acitizen 'of ythe United States, residing `in the city and county of Philadelphia, State yof Pennsylvania', have invented a new and useful Improvement in Bicycle-Jacks, whichiinprovernent is fully set forth in the following specication and accompanying drawings.

. My invention-consists of a jackfor snpportinga bicycle or holding the saine in ele- Vated position, the various features ofthe same beinghereinafterset forth. I

. It also consists of means for keeping the steering Wheel to the front, as will fbe hereinafter set forth. Figure 1 represents a side elevation of a bicycle jack embodying my invention. Fig. 2 represents a perspective view thereof. Fig. 3 represents a rear view partly sectional and partly broken away. Fig. 4 represents a modification of a portion thereof.

Similar letters of reference indicate corresponding parts in the several figures.

- Referring to the drawingsz-A designates a frame or stand formed of the front standard B, the base C, and rear standards D, said base consisting of the frontv and rear cross pieces E, and the longitudinally extending p1e ce F, which is secured to said cross pieces E, 1t being noticed that the several standards rise from the base C." On the side of the base, opposite to the cross 'pieces,E,are -e X-.

tensions E', E2, which may be said to form continuities of said pieces,whereby the'base is made broad,and thus prevents overturning or tilting of the frame A, especially asthe -r Y standard B rises from theextension E of the base, owing to the space required at thefront of the frame aside of said standard.

The upper end of the standard Bis deflected laterally, as at G, and on the same is mounted the grooved roller H, which may be formed of soft rubber or other suitable material, or

` of a hard substance faced with said material,

for preventing abrasion ofthe portion of the f bicycle which may come in contact with said roller.

In the upper endsof .the rearstandards D are sockets J, J', the inner side of each vof which is recessed as at K, to form a seat for the step L and nut M, at the outer ends of the axle or the rear wheel of the bicycle, orin M and the pinion P thereof, thus actingas a 6ol v,

keeper, by which provision springingy apart of the standards D is prevented;

`On the standardB, is a sleeve Q of'softl I rubber or other elastic lor flexible material,-

which serves to prevent abrasion or scratching of the part of the bicycle that vis liable to come in contact with said standard, as the bicycle is being applied to or removed from the frame.

The operation is as' followsz-The` bicycle is raised, and the reach or back-bone thereof placed on the roller H, and the bicycle as supported andl guided on said'roller, is moved until the parts on the ends of the rear axle are above Athe sockets J, after which the bicycle is lowered at its rear end, so that said parts enter the recesses K, it being seen that the bicycle is controlledrat bothends on the frame A, and held elevated so that its wheelsy clear the Hoor or ground, by which provision the bicycle is prevented from falling overor overturning, it may bemountedand operated for they purpose of teaching others to ride thereupon, or for practice, exercise, testing, dto., the wheels may be conveniently cleaned and lubricated, the saddle, treadle's'and other parts adjusted, and otheradvantages are pref sented due to the elevatedsnpportof the bicycle. y The bicycle maybe raised` clearl of t-hev roller vand sockets in whichit is seated,

and thus again placed on the flooror ground, and runas usual. ,v i .p Y

yVVhenzthe bicycle is supported on the'frame,

the front `wheel is liable to-turn, andthus oc- Vcupy an lobjectionable position] To prevent v 95 this, I employ chains or cordsR,oneend of each of which is connected witheyes S on vthe base C, and the other end is adapted tobe attached der to prevent strain ltoer avoidblows yon the parts with which said chains are` connected,

receive in its tendency to turn, there are secured to said chains in the 4length thereof,

kdue to any motion that? the front wheel' may seen in Fig 2.

the coiled springs U,Which renderthe former somewhat elastic in their nature, the effect of which is evident. The ends of the chains have rubber rings V connected with them, for preventing scratching of the foot rests of the bicycle onpwhich they are hung, and the standard B is provided with'hooks W, to sustain the chains when not .in use, as will be Projecting from one of the rear standards D is a perch X,on which the foot is placed when itis desired to mount the bicycle or dismount` ltherefrom when supported on the stand.

The under side of the base C, is provided with sockets Y, in Which are fitted the cushions Z of rubber or other suitable elastic or flexible material, the friction of which with the floor or ground serves to prevent shifting of the stand, especially when the bicycle as supported is occupied and operated for learning, exercise, &c. y

In order to prevent the frame from tilting forward, especially when the bicycle is occupied, thebase C, has at itsfront end, an extension Cv', which lengthens said frame, especially in front .of the roller I-I, and prevents the front cross bars E, E', acting as an axisl or fulcrum on which the frame may turn.

In Fig. 4, I show forks J in lieu of the sockets J, at the side of one of which is a bifurcated arm N', which is similar to the bifurcated arm N in the other figures, for supporting theaxle of the wheel, and preventing springing apart of the standards D', which support said forks and arm.

Having thus described my invention, what I claiml as new, and desire to secu re by Letters Patent, is-

l. In a bicycle jack, a base consisting of a longitudinally-extending piece, cross pieces extending on opposite sides of said longitudinally-extending piece, standards secured to one of said cross pieces and having recessed portions at their yupper ends, and a standard .secured to a second cross piece and having a laterally deliected upper end with a grooved roller thereon, said parts being combined substantially as described.

2. A bicycle jack having a frame with cross pieces extending on opposite sides of a longitudinally-extending piece thereof, standards on said frame, one having a defiected upper end provided With a grooved roller, and the other standards having sockets on their upper ends with recessed sides, said parts being combined substantially as described.

3. A bicycle jack having a frame consisting of thelongitudinally-extending piece F, vthe cross pieces E extending on opposite sides of said piece F, and the extension'C, the front standard B on one of said cross pieces,land having an upper deflected end With'a roller there-on, and the rearstandards D with upper recessed ends, said parts being combined substantially as described.

4. In a jack for a bicycle,&c., the frame thereof having chains 0r cords which are attachable to the steering Wheel ofthe bicycle, and provided with means for rendering the same elastic, substantially as described.

5. Theframeofabicyclejackhavingchains or cords connected at one end with the base thereof, and elastic rings connected with the other ends thereof, substantially as described.

6. The frame of abicyclej ack having chains or cords connected therewith, and hooks on which the upper ends of said chains or cords are attachable, substantiaily as described.
